Purification and partial amino acid sequence of proteins from human epidermal keratinocyte conditioned medium.
Keratinocytes are the main cell type of the epidermis. They secrete a variety of proteins and peptides that have diverse roles in epidermal physiology. In this report, we present purification and partial amino acid sequence of LEKTI, a serine proteinase inhibitor, and DAN (NO3) zinc-finger protein, a tumor suppressor protein of neuroblastoma, from human keratinocyte conditioned medium. Epiderma...
متن کاملPurification of two forms of colony-stimulating factor from mouse L-cell-conditioned medium.
A modified procedure for the purification of the colony-stimulating factors (CSFs) in mouse L-cell-conditioned medium is used to isolate two forms of CSF, which are separable by reversed-phase high performance liquid chromatography with 300-A pore size supports. The specific biological activity of these CSFs (2 X 10(9) colonies/mg) was considerably higher than has been achieved by other methods...
متن کاملfunctional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner
نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
Purification of a multipotential colony-stimulating factor from pokeweed mitogen-stimulated mouse spleen cell conditioned medium.
A factor able to stimulate the proliferation and differentiation of multipotential stem cells and progenitor cells of the granulocyte-macrophage, eosinophil, and erythroid lineages as well as being able to maintain factor-dependent cell lines in culture has been purified from pokeweed mitogen-stimulated mouse spleen cell-conditioned medium. The factor was purified over 2 million-fold by sequent...
متن کاملProteins from human oviductal tissue-conditioned medium modulate sperm capacitation.
BACKGROUND Spermatozoa acquire the ability to fertilize an oocyte when they become capacitated. Capacitation takes place when sperm pass through the female reproductive tract, interacting with female fluids. Both tyrosine phosphorylation of sperm proteins and the ability to respond to acrosome reaction (AR) inducers have been associated with sperm capacitation. Recent data indicate that conditi...
